Incorrect resistor value in L6 LEDs in Intro to Electronics?

I received this email:

My name is Rohan, and I am currently working through your physical computing interactive textbook. First off, thank you so much for creating this incredible resource!

In lesson 6, the image in this section seems to have a mistake: the resistor value in the right circuit is 330Ω. Unless I am mistaken, I believe it should read 470Ω.

I just wanted to bring this to your attention, in case you would like to fix it. Thank you for your time!

I have now verified that this is indeed a problem. We should 330 in both the left and right figures. But the right figure should show 470.

Now fixed locally. Pushing change in a second:
